[@psarkar.]

The speed of sound in a medium depends on temperature of the medium. The speed of sound decreases when we go from solid to gaseous state. In any medium as we increase the temperature, the speed of sound increases. For example, the speed of sound in air is 331 m s-1 at 0 ºC and 344 m s-1 at 22 ºC. 👆 Copy from NCERT Book তাহলে উষ্ণতা বৃদ্ধির সাথে শব্দের গতিবেগের সম্পর্ক ব্যস্তানুপাত হয় কিভাবে ? স্যার এটা আমি বুঝতে পারলাম না ।
